Quasi-three-dimensional volume imaging provides an inexpensive means of
evaluating the usefulness of three-dimensional imaging. The technique works
most efficiently with water-skin interfaces and therefore we investigated
its application in obstetrical ultrasonography. Three-dimensional
perspectives of the normal and abnormal fetal head and face were
spectacular and at times provided more information than the two-dimensional
images. The ability of an inexperienced observer to interpret the
three-dimensional image more easily may have a role in training
sonographers and counseling parents whose fetuses have structural defects.
Volume imaging has certain limitations and can only be used as a
complementary technique.
